I played for a half hour. It was fun to walk around the town and explore, trying to almost treat it like a stealth game and break off one guard at a time while keeping up my health with townspeople. I made it into the keep and even to the king one time, but I died almost immediately.
I wish I'd been able to become more powerful by draining lots of people; it sounds like something like that might have been planned. It would have been nice if the drain had speeded up the more people I drained, or just letting me move faster for every 5 people I drained or something. That phrase in the tutorial--something about "The king becomes weaker the more guards and citizens you drain"--was very intriguing.
Clearly a lot of effort went into the art and animations. I liked the pulling, draining and floating animations, and the jump (though I couldn't find much of a use for it). The NPCs had some decent reaction animation to being picked up. I also liked the atmosphere of the town, the low-poly trees were really pretty, and the castle on the hill was very imposing.
The controls were quite janky. :P The "special move" (???) had a lot of windup time, but it was a kind of fun challenge to time the knockdown correctly. The pulling move was also kind of fun. I wish there had been an indicator of who was in range and who wasn't for those, but I can understand why not.
I also really appreciated the music. It was used to help establish the mood and even to help guide you to the right path; it would fade out when you were wandering far afield. The church was really interesting, too; I feel like more was probably planned with that. I wish I'd been able to finish it. I honestly would love to beat it/see the ending, so I'll look forward to an update if you guys are planning one.
Really good job! I think it's great that you got a team together and accomplished so much in a week!
